I've installed Monique's Individual Aging mod as updated for Apartment Life by Ancient Highway, because I initially only wanted to disable aging for one premade sim. However I ended up disabling aging for the whole family (by clicking on each sim individually) and I thought that at this point I might as well uninstall the mod and use the aging off cheat command instead. The thing is though, aging control over individual sims seems like something that could come in handy, so I'm actually thinking of keeping the mod but I'm not sure if it'll conflict or cause other issues with the aging off command. Does anyone have experience with that?

Personally i would keep the mod and not use the cheat. The cheat seems to be buggy from some help questions i've seen asked on here.

Oh, I didn't know that. Thanks! I guess I'll keep the mod. :D

Another vote for the mod, used it for years. I like to use it on a sims birthday so they don't age until they have blown out their birthday cake candles.
The only issues are on occasion I forget to turn it back on or I click it by accident.

Never used the mod, but I've used the cheat and never had any problems with it.
